The chlorinator is clamped on the chlorine cylinder valve. The ejector assembly is normally attached to the solution diffuser at the point of injection. A vacuum line connects these two units.
Water, under pressure, is forced through the ejector nozzle which creates a strong vacuum in the ejector body.
This pulls gas into the ejector through a special back-flow check valve and then into the nozzle outlet.
The gas mixes with the ejector water and is discharged through the diffuser into the water being treated.
The ejector vacuum is transmitted back to the chlorinator through the vacuum line; then through the rate valve and the flow meter and to the back of the chlorinator diaphragm.
With sufficient vacuum, the diaphragm moves backward, opening the spring-loaded inlet regulating valve to allow chlorine to enter from the cylinder.
The chlorine passes through the flow rate indicating meter, flow rate adjusting valve and to the ejector.
